RESUMO
OBJECTIVES: To compare procedural and in-hospital outcomes of patients undergoing sutureless (Perceval, Livanova PLC, London, UK) and rapid deployment (Intuity Elite, Edwards Lifesciences, Irvine, CA, USA) aortic valve replacement (group 1) versus sutured aortic valve replacement (group 2). METHODS: Patients receiving isolated aortic valve replacement between 2014 and 2020 were analysed using data from the Sutureless and Rapid Deployment International Registry. Patients in group 1 and group 2 were propensity-score matched in a 1:1 ratio. RESULTS: A total of 7708 patients were included in the study. After matching, 2 groups of 2643 each were created. Patients in group 1 were more likely to undergo minimally invasive approaches and were associated with shorter operative times when compared with group 2. Overall in-hospital mortality was similar between groups. While an increased risk of stroke was observed in group 1 in the first study period (2014-2016; relative risk 3.76, P < 0.001), no difference was found in more recent year period (relative risk 1.66, P = 0.08; P for heterogeneity 0.003). Group 1 was associated with reduced rates of postoperative low cardiac output syndrome, atrial fibrillation and mild aortic regurgitation. New pacemaker implant was three-fold higher in group 1. CONCLUSIONS: Our findings showed significant differences in procedural and clinical outcomes between the study groups. These results suggest that sutureless and rapid deployment aortic valve replacement should be considered as part of a comprehensive valve programme. The knowledge of the respective post-aortic valve replacement benefits for different valve technologies may result in patient-tailored valve selection with improved clinical outcomes.

PURPOSE: Aortic stenosis (AS) is the most common cause of adult valvular heart disease. In the past decade, minimally invasive surgery (MIS) to treat AS has gained popularity, especially if performed in combination with rapid deployment valves (RDVs), which shorten cross-clamp time (XCT). This study examines specific outcomes and related costs of aortic valve replacement (AVR) before and after the introduction of RDVs. METHODS: We used the AVR simulator, an economic model developed to correlate cost and resource utilization associated with the adoption of RDVs, to compare 2 scenarios: (1) a current scenario based on standard AVR practices and (2) a proposed scenario based on increasing use of RDVs and an MIS approach. Both scenarios involved 3 subgroups of patients treated with (1) conventional AVR, (2) MIS, and (3) AVR combined with a coronary artery bypass graft. The current scenario (status quo) involved patients treated with traditional biological valves, and the proposed scenario involved patients who underwent implantation with an RDV. The AVR simulator was fed with real-world input data to estimate complication rates and resource consumption in the proposed scenario. Real-world input data for this analysis were obtained from patients diagnosed with a symptomatic heart valve disease between 2015 and 2018, at Clinica-San-Gaudenzio, Novara, Italy. Lastly, the AVR simulator estimated hospital savings by comparing the 2 scenarios. FINDINGS: A total of 132 patients underwent implantation with a traditional biological valve, and 107 were treated with a commercial valve system. The RDV was associated with an increase of 52% of patients undergoing MIS, which generated a 6.1-h reduction of XCT and a total savings of 6695. RDVs also reduced intensive care unit (ICU) and hospital ward length of stay (LOS), leading to savings of 677 and 595 per patient, respectively. Mortality and blood transfusions also improved. The savings for the hospital (related to shorter XCT, hospital ward LOS, and ICU LOS) amounted to 144.111. Our findings were consistent with data gathered from our real-word setting, and results of a sensitivity analysis indicate that our findings were robust across different possible situations. IMPLICATIONS: Switching to RDVs and MIS procedures for AVRs was associated with a reduction of costs related to XCT, hospital ward LOS, and ICU LOS. Hospitals can upload literature- and experience-based clinical and cost values to the AVR simulator to estimate a hospital's performance with the introduction of RDVs compared with standard biological valves. This study was not randomized, so more extensive studies could confirm our results in the future.

We report a case of a 57-year-old female with dextrocardia and a solitary kidney. A patch aortoplasty for isthmic aortic coarctation repair was performed 40 years before when she was admitted to our department for dyspnea. Computed tomography scan showed a giant and saccular 10-cm diameter patch false aneurysm. The ascending aortic diameter was 34 mm and the echocardiography confirmed a severe aortic regurgitation of a bicuspid aortic valve. We decided to perform a 2-step approach: biologic aortic valve and ascending aorta replacement with total debranching of the epiaortic vessels and thoracic endovascular aneurysm repair for complete false aneurysm exclusion.

INTRODUCTION: The association of pure aortic regurgitation and porcelain aorta represents a challenging situation. In the Transcatheter Aortic Valve Implantation (TAVI) era, porcelain aorta (PA) becomes an additional risk for patient treatment and sometimes serves as the primary indication for the TAVI approach, even in low-risk patients. Devices currently on the market are not yet validated for the treatment of pure aortic regurgitation (AR) in PA and mid/long-term results are still not available. Furthermore, small calcified sinotubular junction and the association of small Valsalva sinus with low origin of coronaries ostia represent a relative contraindication of TAVI. PRESENTATION OF CASE: We report a case of severe symptomatic AR associated with a PA in a patient successfully treated with a sutureless Perceval valve. DISCUSSION: The sutureless Perceval valve may represent an excellent option. This valve requires less manipulation of the ascending aorta and no manipulation of the aortic annulus except for the aortic valve leaflets removal. Furthermore, it can be implanted also in a small and calcified sino-tubular junction because the valve is collapsible before the implant. CONCLUSION: The present case represents a proof that self-expandable cardiac valve technology can be employed to treat, either by surgery or by catheter, selected cases of AR. We have observed an excellent mid term result with no paravalvular leak at 2 years.
RESUMO
BACKGROUND: Repeat surgery of the chronically dissected aorta following repair of a Type-A acute aortic dissection (AAD) still represents a challenge. The proposed surgical options are as follows: (1) staged procedure with elephant trunk (ET) technique, (2) traditional frozen elephant trunk (FET) intervention, and (3) beating heart cerebral vessel debranching followed by thoracic endovascular aortic repair (TEVAR). However, a marked enlargement of the proximal descending thoracic aorta might make it difficult to perform FET/ET intervention. Furthermore, because in conventional surgery for AAD, a prosthetic graft replacement is generally limited to the ascending aorta, and in repeat surgery, this short Dacron graft rarely provides enough room to allow a beating heart cerebral vessel debranching and obtaining a reliable landing zone for the implantation of a firmly anchored stent graft. METHODS: We retrospectively reviewed all the five consecutive patients treated in our institution, between 2014 and 2017, for chronic aortic dissection after successful surgical treatment of acute Type-A aortic dissection with graft replacement limited to the ascending aorta. The five patients underwent repair utilizing a modified FET technique with total aortic arch and upper descending aorta exclusion without touching the native dissected aorta. RESULTS: No early- or midterm mortality was observed. Mean time interval between the initial and the reoperative procedure was 26 months (range, 3-80 months). No patient had a minor/major neurologic event. Mean circulatory arrest time was 16 minutes (range, 11-25 minutes). Mean follow-up time was 22 months (range, 9-42 months). CONCLUSIONS: We report our initial experience with a modified FET technique realized by anastomosing the stent graft with the previously implanted ascending aortic graft in Hishimaru's zone 0 and by rerouting all cerebral vessels without "touching" the native chronically dissected aorta. A larger number of patients and a longer follow-up will be required to confirm these initial encouraging results.
RESUMO
We report the case of a 33-year-old man presented with a posttraumatic 20-mm left ulnar artery aneurysm without intraluminal thrombus in the left hypothenar eminence. The patient reported left hand paresthesia. Because of symptoms and the embolic risk, we decide to plan an aneurysm resection and an interposition graft with inverted basilic vein for adequacy diameter (â¼2 mm), but an end-to-end anastomosis was performed instead. We think that the posttraumatic distal artery aneurysm could be treated without a bypass but, after a meticulous anatomic dissection, with a microvascular anastomosis between the artery stumps.

BACKGROUND: In the absence of a standardized safe surgical reentry strategy for high-risk patients with large or anterior postoperative aortic false aneurysm (PAFA), we aimed to describe an effective and safe approach for such patients. METHODS: We prospectively analyzed patients treated for PAFA between 2006 and 2015. According to the preoperative computed tomography scan examination, patients were divided into two groups according to the anatomy and extension of PAFA: in group A, high-risk PAFA (diameter ≥3 cm) developed in the anterior mediastinum; in group B, low-risk PAFA (diameter <3 cm) was situated posteriorly. For group A, a safe surgical strategy, including continuous cerebral, visceral, and coronary perfusion was adopted before resternotomy; group B patients underwent conventional surgery. RESULTS: We treated 27 patients (safe reentry, n = 13; standard approach, n = 14). Mean age was 60 years (range, 29 to 80); 17 patients were male. Mean interval between the first operation and the last procedure was 4.3 years. Overall 30-day mortality rate was 7.4% (1 patient in each group). No aorta-related mortality was observed at 1 and 5 years in either group. The Kaplan-Meier overall survival estimates at 1 and 5 years were, respectively, 92.3% ± 7.4% and 73.4% ± 13.4% in group A, and 92.9% ± 6.9% and 72.2% ± 13.9% in group B (log rank test, p = 0.830). Freedom from reoperation for recurrent aortic disease was 100% at 1 year and 88% at 5 years. CONCLUSIONS: The safe reentry technique with continuous cerebral, visceral, and coronary perfusion for high-risk patients resulted in early and midterm outcomes similar to those observed for low-risk patients undergoing conventional surgery.

Patients with aortic pathology involving the ascending aorta, the arch, and the descending aorta present a complex surgical challenge. A one-step hybrid procedure with ascending aorta repair, arch debranching, and frozen elephant trunk is reported in five patients. Left subclavian artery side graft cannulation is used to perfuse the spinal cord during circulatory arrest time.
RESUMO
We report a case of giant cell arteritis manifesting as upper limbs ischemia due to a complete occlusion of the left subclavian artery and a high grade stenosis of the right subclavian artery. We decided to use a combined medical, surgical and endovascular treatment followed by long term treatment with methotrexate. After 4years the patient had no signs or symptoms of relapse. In our personal experience long term treatment with Methotrexate demonstrated a certain efficacy in avoiding relapse of the inflammatory phase and in maintaining stability of results in this kind of disease.
